Galaxy-Galaxy Lensing in the FORS Deep Field
We demonstrate the presence of a galaxy-galaxy lensing signal of z=0.5-1.0 foreground galaxies by analyzing the distortion of z=2.5-4.5 background... -
The Mass Function of Field Galaxies at 0.4 < z < 1.2 as Derived from the MUNICS K-Selected Sample
We derive the number density evolution of massive field galaxies in the redshift range 0.4 < z < 1.2 using the K-band selected field galaxy sample... -
Nuclear Stellar Disks in Spiral Galaxies
We report the discovery of a nuclear stellar disk in 3 early-type spirals, namely NGC 1425, NGC 3898 and NGC 4698, revealed by WFPC2/F606W images out... -
Gas Minor-Axis Velocity Gradients in Early-Type Spiral Galaxies
We measured a remarkable gas velocity gradient along the minor axis of 5 early-type spiral galaxies. This phenomenon suggests the presence of a... -
The Evolution of Distant Cluster Spirals
Ground-based and HST observations indicate that the disk galaxy population in rich galaxy clusters has experienced remarkable evolution since z = 1.... -
Measuring Galaxy Disk Mass with the SparsePak Integral Field Unit on WIYN
We present first results from the commissioning data of the SparsePak Integral Field Unit on the WIYN telescope. SparsePak is a bundle of 82 fibers,... -
Constraining the Mass Assembly in Ellipticals from ERO Clustering
The redshift evolution of clustering is a powerful tool to constrain the models of galaxy assembly. In particular, the strong clustering of EROs, if... -
Evolution in the Linewidth-Magnitude Relation to z > 1 from the DEEP Groth Strip Survey
Galaxy kinematics are potentially a powerful tool to measure the evolution of Tully-Fisher-type relations and to see how properties of distant... -
First Evidence for an Extended Dark Halo in the Draco Dwarf Spheroidal
We present a new velocity data set in the Draco dwarf spheroidal, containing the velocities of 159 giant stars extending to large radii. We fit this... -
On the Black Hole - Bulge Mass Relation in Active and Inactive Galaxies
New virial black-hole mass estimates are presented for a sample of 72 AGN covering three decades in optical luminosity. Using a model in which the... -
Stellar M/L Ratios and Spiral Galaxy Dynamics
We present a simple technique to estimate mass-to-light (M/L) ratios of stellar populations in local universe galaxies based on two broadband... -
A Radio-Quiet Radio Galaxy at High Redshift
We report on observations of CXO52, a Type 2 quasar at redshift z = 3.288 identified as a hard X-ray source in a deep observation with the Chandra... -
The Masses of Distant Galaxies from Optical Emission Line Widths
Promising methods for studying galaxy evolution rely on optical emission line width measurements to compare intermediate-redshift objects to galaxies... -
The Evolution of the Mass-to-Light Ratio of Field Early-Type Galaxies
I report on our recent measurement of the Fundamental Plane (FP) of field early-type galaxies (E/S0) in the redshift range 0.1 < z < 0.66, and... -
The Properties of Low-Redshift Damped Lyman Alpha Galaxies
Damped Lyman alpha (DLA) galaxies are those which give rise to the DLA lines seen in the spectra of background QSOs, indicative of neutral hydrogen... -
The Assembly of the First Galaxies
The first galaxies formed at high redshifts, and were likely substantially less massive than typical galaxies in the local universe. We argue that... -
Kinematics of ISOCAM Selected Star-Forming Galaxies at z $\sim$ 1 in the Hubble Deep Field South
The various deep ISOCAM surveys revealed a new class of infrared luminous galaxies which are characterized by a high rate of evolution and are found... -
HST Imaging of a z=1.55 Old Galaxy Group
We present high-resolution imaging in the rest-frame optical of the weak radio source LBDS53W091. Previous optical spectroscopy has shown that this... -
The Assembly of Galaxies from a Wide/Deep IR Survey
We show how deep multicolor imaging surveys may be used to trace the assembly of stellar mass in galaxies at different redshifts. Deep multicolor... -
Prospects with ALMA
The Atacama Large Millimeter Array will greatly enhance our ability to study the dynamics and masses of galaxies and their components at both low and...
